org.apache.commons.fileupload.FileUpload

public class PortletFileUpload
extends FileUpload

High level API for processing file uploads.

This class handles multiple files per single HTML widget, sent using multipart/mixed encoding type, as specified by RFC 1867. Use FileUploadBase.parseRequest(HttpServletRequest) to acquire a list of FileItems associated with a given HTML widget.

How the data for individual parts is stored is determined by the factory used to create them; a given part may be in memory, on disk, or somewhere else.
